Creating a massive, intricate network that envelops almost all of Gotham, with tunnels that even branch far off into the outskirts, it has been theorized that whoever acted as the architect for the sewer system had been smoking something particularly potent. Unlike your conventional, sensible sewer system, the Gotham network is a veritable maze, full of drainage ditches, massive tunnels, abandoned filtration stations, all bearing an architecture almost as elaborately Gothic as Wayne Tower. There are certainly plenty of places for ne'er-do-wells to hide themselves... assuming you can stand the smell, of course.
